Easy ways on how to grow onion

Twenty to 50 onions could grow in 1 to 1 sq legs of space. Onions are easily grown in odd spaces alongside both slower and faster growing vegetables. Green onions can be ready in 20 to 1 month after planting. Dry bulb onions may take 100 to 175 days to reach maturity. Onions can be grown from seeds, sets, or transplants. Growing onions from seed may take just as much as five months. You’ll find seed for many varieties or cultivars of onions. Select bulb or bunching onions depending upon your intended use. Bulb onions can vary from the small pearl onions to very large Spanish types.

Growing conditions for onions

Onions grow tops in cool weather and form bulbs in warm weather. Long day onions require extended hours of daylight of 14 to 16 hours per day to reach maturity. Short day onions grow best in mild winter southern latitudes. Turn lots of well aged compost and manure in the onion bed in advance of planting, turn the ground for at least 8 inches deep. Sow onion seeds indoors 8 to 12 weeks before the last average frost date. Avoid planting onion seed directly in the garden till the soil temperature has reached 50F. Outdoors sow onion inches deep and 1 inches apart.

Using seedlings to grow onions

Growing onions from seed will give you the widest choice of varieties. Seedlings can be transplanted to the garden at the beginning of spring once the soil can be worked normally about 2 to 3 weeks before the last frost when the soil temperature is at least 40F, the air temperature must be at least 45F. Set bulb onion seedlings one to two inches deep depending upon the size of the bulb and 4 to six inches apart. Onions grown from transplants mature faster than onions grown from seed. Set bulbs to one inches deep and 4 to six inches apart depending upon the size of the bulb at maturity.

Maintenance and care

Onions sets are frequently labeled Red, White, or Yellow you might not know the exact variety you’re growing. Feed onions with a rich fertilizer, like fish emulsion, early in the season to build large plants and bulbs. At midsummer or about a month before harvest after bulbs have formed and once the necks of the onions start to soften, cut back on food and water and allow bulbs to mature in drier, less fertile soil. Since onions leaves are thin and strappy they don’t block the sun from the soil which, in turn, allows weed germination. Onion beds require more weeding than other vegetable beds.
